AUXILIARY BUFFER FOR SHOCKERS.

Specification of Letters Patent.

Patented Jan. 20, 1920.

Application filed December 19, 1917. Serial No. 207,863.

To all whom, it may concern:

Be it known that I, CLEMMA R. RANEY, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Auxiliary Buffers forShockers, of which the following is a full, clear, and exactspecification.

This invention relates to grain shockers, and more particularly totrippin mechanism for throwing into operation t e delivery fork whichdelivers the sheaves to the shock receptacle; The invention has beenillustrated in connection with the Raney type of shocker, such as shownin Patent 0. 1,222,798, Raney, April 17, 1917. In this type of machinethe releasing means for the delivery fork comprises a rock shaftpositioned at one side of the fork, and having upstanding tines whichare so located as to be engaged by the sheaf as it is discharged fromthe binder deck. When the sheaves engage these tines the shaft isrocked, and by means of a suitable clutch the sheaf delivery fork isthrown into operation. Although provision has been made in this shockerfor stopping the discharging mechanism of the binder while the sheafdelivery fork of the shocker is operating, instances have occurred inwhich the discharging mechanism of the binder has discharged sheaveswhen the sheaf delivery fork of the shocker was not in position toreceivethem. When a sheaf has been discharged from the binder, and.

the delivery fork is not in position to receive it the rock shaft isrotated and is sometimes held in its rotated position, and as thedelivery fork returns to sheaf receiving position another sheaf will bedischarged, and will rotate the rock shaft still farther. This continuedrotation has occasioned the breaking or twisting of the rock shaft,thereby putting the machine out of operation.

With the above noted difficulties in mind I have devised my presentinvention in which provision is made for taking up these unusual strainson the rock shaft or trip shaft, thereby avoiding the breakage of the ashaft.

tion, of my improved rock shaft construction;

Fig. 8 is a section on line 3-3 of Fig. 2 looking in the direction ofthe arrows; and

Figs. 4 and 5 are detail views on an enlarged scale showing theconnection between the trip shaft and the clutch controlling member 36.I

The front portion of the shock receptacle 10 is supported through theusual braces 11 on the transversely extending supporting member 12secured to the frame of the binder, and extending outwardly beneath thebinder deck. The sheaf delivery fork 13 is carried by a shaft 14,operated by driving mechanism 15, and controlled by a clutch 16. Thisdriving mechanism and clutch are fully illustrated in my prior patents,and attention is directed to Patent No. 1,222,798 above referred to.

The trip shaft 17 is journa-led at one end in suitable journaling meansdisposed on the under side of the supporting member 12, and at the otherend is connected to the frame of the shocker in a manner hereinafterdescribed. This trip shaft carries on its rear end a sleeve 18, which isrotatably mounted on the shaft, and is held against longitudinalmovement by the cotter pin 19. This sleeve is provided with an outwardlyextending offset portion 20,.havinga projection 21 on the outer endthereof through which extends a link 22. This, link 22 carries a spring23 on its outer end, and a nut 24 for adjusting the tension of thespring. The innner end of the link 22 is pivotally connected to anoutwardly projecting extension 24 formed integral with a clamp 25, whichis secured to the trip shaft 17. The link 22 is screwthreaded and isprovided witha nut 22, as illustrated in Figs. 2 and 3 for adjusting therelative positions of the extensions 20 and 24.

From the above description it will be seen that the rocking motion ofthe trip shaft 17 is communicated through the clamp 25, link 22 andsleeve 18 to the outwardly extending bifurcated portion 26 of saidsleeve. The bifurcated portion 26 forms one portion of a hingedconnection, the other portion of which is embodied in the outwardlyextending bifurcatedportion- 27 of a casting 28 pivotally secured to theframe of the shocker.

This casting is pivoted on a stub shaft 29 outward rotational movementof the rock.

shaft 17 by engaging the frame 10 of the shocker. The casting 28 alsocarries an inwardly extending projection 32, the end of which is pivotedto a link 33, which extends across the front of the shocker frame, andcarries at its opposite end the rear end of a rod 34, which extendsforwardly, and its I forward end is bent upwardly to a position on thebinder deck where it is engaged by the sheaves as they pass from thedischarg ing mechanism into the binder. This construction is fullyillustrated in the patent above referred to, and hasv therefore not beenshown in detail in this application.

The casting 28' also carries at its rear end an outwardly projectingclamp 35, in which is carried an upwardly extending locking member. 36,which is bent inwardly at its rear end, as shown at 37, to form a dogwhich controls the operation of the clutch 16, thereby controlling theoperation of the sheaf delivery fork. The rock shaft 17 is provided withupwardly extending sheaf guiding tines 38, which are engaged by thesheaves as they are discharged from the binder deck. The position ofthetines 38 and rock shaft 17 can be controlled by means of theadjustment of the nut 22 on the link 22. The tines and the rock shaftare first inserted in the clamp 25 in the approximate position ofadjustment, but by changing the position of the nut 22 and causing theextensions 20 and 24: to move 'relativeto each other, a finer adjustmentma be obtainedv he operation of the deviceis as follows: When the sheafis discharged from the binderdeck it engages the tines 38, therebyrocking the shaft 17, the sleeve 18, casting .28 and pawl 37, andreleasing the sheaf delivery fork 13. The tines 38 also perform. thefunction of arresting or stop- I ping the sheaves. after theyaredischarged from the binder deck, and of guiding the sheaves on to thesheaf delivery fork 13. If the rock shaft l is in its normal position.when engaged by the sheaf there will b'e-substantially no relativerotation between the rock shaft and thesleeve 18, but should the shaftbe disposed in such a position that the tines 38 are inclined rearwardlywhen a sheaf. is discharged from the binder deck,

and engages thesetines in which position the pin 31 engages frame 10,the shaft 17 will be rotated, and through the clamp 25, l nk 22 andspring. 23 the rotatigm of the shaft will be communicated to the sleeve18,

the spring takingup the excess rotation of the shaft. The point ofrotation of shaft 17 in which the adjustable pin 31 engages the frame10, therefore determines the point of operation of the resilientconnection between the shaft 17 and sleeve 18. In this way the excessrotation will do no damage and the shaft will not be broken under theunusual strain put upon it.
